Current flag:
Nice Flag! It’s a really appealing tricolor, so I can’t really make it better. The colors are taken from the unofficial former flag of Brabant. However, the proportions are really weird. 13:15.
My Redesign:
The basic design is taken from the Lesser Arms of the Royal House. I thought it looked kind of cool. The green band is a very simplified crown, and I actually don’t know what the stripes represent.
